摘要
本文选取三峡水利枢纽永久船闸二闸室桩号15+583代表性断面,通过地表测绘与地质编录、钻孔勘探、压水试验、全孔壁数字成像、物探测试、弹变模测试等综合勘察手段,并结合岩体变形监测成果等,查清了中隔墩岩体的工程地质特征、岩体卸荷松驰范围、物理力学性质及其稳定性.
No. 15 +583 pile of the second lock chamber of Three Gorges permanent navigation lock is chosen as the representative section. Based on earth mapping and geological recording, small - calibre probing, packer test, borewall digital imaging, physical probing test of modukus of elasticity and deformation and so on, relaxation characteristics of septi - mound rock mass unloading and influencing factor are analyzed and macro qualitative evaluation of stability is given, which lays the foundation to deal with projects.
